论文摘要
在硬性独家过程中的核普遍分配（GPD）的测量，例如深度虚拟的康普顿散射（DVC），将是高亮度的新一代实验的主要成就之一，例如在杰弗森实验室（Jlab）（Jlab）中使用12 gev Electon beam和其他所有这些实验的实验，这些实验是所有的，这些beam and the the the the the the the plan currider plan infore norpal currider coll and plan infore nufore infuteR coll infore nufure corn infore nufore infuterne nive infore nufore infutern and Future and Future。 JLAB的CLAS合作最近证明了有可能解除两个不同的核DVC渠道，即连贯和不连贯的渠道，这是朝着核和边界核子GPD迈进的第一步，在该领域开辟了新的令人兴奋的观点。在这种情况下，理论上的精确计算，最终是现实的，成为强制性的。对现实研究负担得起的光核可以安全地估算出常规的核效应，因此可以暴露出可能的外来效应，起着重要作用。将总结用于光核的GPD计算的状态，尤其是$^3 $ HE和$^4 $ HE，将会介绍一些更新。未来几年的前景与未来设施的新一系列测量有关。
The measurement of nuclear generalized parton distributions (GPDs) in hard exclusive processes, such as deeply virtual Compton Scattering (DVCS), will be one of the main achievements of a new generation of experiments at high luminosity, such as those under way at the Jefferson Laboratory (JLab) with the 12 GeV electron beam and, above all, those planned at the future Electron Ion Collider. The CLAS collaboration at JLab has recently demonstrated the possibility to disentangle the two different channels of nuclear DVCS, the coherent and incoherent ones, a first step towards the measurement of GPDs of nuclei and of bound nucleons, respectively, opening new exciting perspectives in the field. In this scenario, theoretical precise calculations, ultimately realistic, become mandatory. Light nuclei, for which realistic studies are affordable and conventional nuclear effects can be safely estimated, so that possible exotic effects can be exposed, play an important role. The status of the calculation of GPDs for light nuclei will be summarized, in particular for $^3$He and $^4$He, and some updates will be presented. The prospects for the next years, related to the new series of measurements at future facilities, will be addressed.
